She calls him a great dad, but he's actually old enough to be her grandfather.

Ekaterina Ivanova, 20, tells this month's Grazia magazine that she might want to start a family with wrinkled Rolling Stones guitarist Ron Wood.

"Maybe it would be nice – but not for at least ten years," she muses. ‘I’m young, so I definitely don’t want a baby yet. And Ronnie’s a great dad, but I don’t know if he’d want any more."

Indeed, it seems Wood, 61, might be more interested in dating children than in having them.

But Ivanova brushes off their 41-year-old age difference.

"This whole age thing is irrelevant," she said. "Not every 60-year-old is going to be doing what people say 60-year-olds should do, like smoking a pipe, and not every 20-year-old likes to go clubbing either."

"We’re like Lego that just clicks together," she adds.

Wood was married to his wife Jo, 53, for 23 years and they have two children who are both older than Ivanova.

Wood and Ivanova are renting a house in London as they shop for a love nest to call their own.
